How the contribution is calculated

The scale of contributions determines the amount each State pays every year. It rests on two objective criteria: national wealth, measured by gross domestic product, and the size of the national art market. States are thus divided into five bands. The amounts shown here are indicative.

The scale is revised by the General Assembly. The State is informed of its band upon accession, then every year.

Payment arrangements are described on the payment page.

The gross domestic product criterion

Gross domestic product measures the State's economic capacity. It is averaged over three years, in order to smooth out cyclical fluctuations and prevent an exceptional year from upsetting the contribution. The data come from recognized international sources.

This criterion accounts for about two thirds of the calculation (indicative proportion). It ensures that a State with a modest economy does not bear a disproportionate burden.

The art market criterion

The second criterion is the size of the national art market, assessed from the statistics of the Studies Directorate and the State's declarations. It reflects the benefit the State derives from the Organization's work: the larger the market, the greater the exposure to the risks of trafficking and counterfeiting.

This criterion accounts for about one third of the calculation (indicative proportion). It is updated every year from the country profiles, notably the market figures.

The five bands

States are classified in one of the five bands according to the result of the calculation. Band 1 corresponds to the minimum contribution of €12,000 per year. Band 5 corresponds to States whose contribution approaches the maximum of €2.4 million.

The intermediate bands progress in steps, which avoids overly abrupt threshold effects. A State that changes band benefits from a two-year transition.

Revision of the scale

The scale is reviewed every three years by a working group made up of representatives of each region. The group examines the evolution of economies, market data and requests from States. It formulates a proposal submitted to the General Assembly, which decides.

No State may see its contribution rise by more than twenty per cent from one revision to the next (indicative limit). This rule protects national budgets.

Special cases and adjustments

A State affected by a disaster, a conflict or a serious economic crisis may request a temporary adjustment. The reasoned request is examined by the Bureau of the Assembly. The adjustment is time-limited and reassessed every year.

States that join during the year pay a contribution calculated pro rata for the remaining months, as explained on the accession contributions page.
